Centro hotsyncs over and over and wont stop

I had the same exact problem with mine and I used "donniepratts'" solution except the first time I guess I didn't clean it good enough, so here is what I did and it works perfectly and is fixed for sure because it would already have done the HotSync thing. Been using it all day.
1) I used a Colgate Cross Action battery powered toothbrush .
2) I dipped the bottom of the phone into about a 1/4" NO DEEPER of Isopropyl (rubbing) alcohol for a few minutes in a clean clear coffee cup.
3) WITHOUT turning the phone over to avoid alcohol from going deep into the phone after taking it out of the alcohol, I scrubbed the heck of a long time occasionally dipping it back into the alcohol to remove dirty alcohol.
4) WITHOUT turning the phone over I placed it on a towel propping it against the wall for a couple hours then used a blowdryer for 10 minutes, again, never turning phone over,................and then...
5) Put the battery back in (remember to take it out before anything!) and it cane right on unlike before and works great.
The contacts were so dirty they were leaking current between them and telling the phone it was syking.
TRY IT, good luck

My palm centro of two years had a similar problem last week and I could not use any phone feature for three says. The self hotsyncing started while on board a flight to Amsterdam. I thought it was a software glitch and tried using even FileZ to disable the redundant pmtracedatabase file that was coming out in the backup log but the hoysyncing still persisted. Finally, after three days of agony, I thoroughly but CAREFULLY cleaned the data port with little alcohol and minute brush and let it to dry for a while. This worked magic I am using the Centro without any problem. To know your Centro has corroded data connectors, you will notice/hear repeated sound coming out from the phone when trying to self hotsync. Your can try this trick/remedy if your device is outside the manufacturers waranty and does not have insurance. Otherwise you may call your carrier for a replacement with a brand new device since this is a well known and documented problem with palm Centro.

okay so heres the deal on palm centro's. the battery and data port on the bottom is EXTREMELY susceptible to moisture damage. any amount of humidity or moisture will wick right into the data port and cause oxidation which is conductive, this is giving it the false hotsync reading. to fix this take the battery out and put a VERY SMALL amount of alchohol on the tip of a toothbrush and scrub the **** out of the prongs..... be carefull as if you use too much you will end up getting alchohol stuck in the coil and it will ruin it when you power it up. what you need to do is make sure its a fresh toothbrush and a little alchohol (almost dry) and after scrubbing the prongs blow dry them with a hair dryer for a while being sure not to heat up the phone too much! after that leave it set for an hour which should be enough for any amount of alchohol to clear!

if this doesnt work you have two options:

1> call in the insurance

2> order a replacement port and resoldier it on!

hope this helps
